1 Claim. 1

This invention relates to window constructions for vehicles, as busses, railway cars, and the like, and has for its object a compact assembly of the window frame and sash in the frame to have a limited swinging opening movement for venti- Vlating purposes without hinged joints, or other joints, which would result in rattling.

It is particularly adapted for window frame and sash assemblies used in air conditioned vehicles where the sash is opened, as a wind wing for Ventilating purposes only at rare intervals, as when the air conditioning system fails.

More specifically, the invention has for its object an assembly of a window frame and swinging sash in which the mounting permitting the swinging of the sash consists merely of a resilient flexible leaf, preferably flat, which requires but a thin space and hence requires no extra thickness of the frame, or the sash, and which contains no joints to become loose and rattle.

The invention consists in the features and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a face view of a window embodying this invention.

Figure 2 is an enlarged sectional view on line 2 2, Figure 1, the contiguous portion of the car body structure around the window opening being also shown.

Figure 3 is a detail isometric view of one of the spring leaves between the window frame and the sash.

In the drawing, I and 2 designate the window frame and the sash respectively, the frame I being mounted in the window opening 3 formed in the body structure 4 of the vehicle. The body structure is here shown as formed with an angular inwardly extending circumferential fiange 5 around the window opening and parallel to the plane of the'sash, this serving as an abutment for the window frame inserted into the window opening from the opposite or outer side of the body structure. This flange 5 is covered by a circumferential sealing strip 6 of flexible compressible material, as rubber, or rubber composition. The window frame is secured in the window opening as by screws 1. A sealing strip 8 is also interposed between the outer edge of the window frame and the wall of the window opening 3. The window frame I and the sash 2 are usually formed of extruded metal.

The sash 2 includes double or spaced glass panels 9 and the mounting I0 therefor of rubber. or rubber composition, the mounting being 1ocated in a channel in the sash and one side of this channel is formed by a demountable retain" ing plate II removable for removing and replacing the glass panels 9 and their mounting I0. This plate is secured to the body of the sash, as by screws I2. The sash 2 nests in the Window frame I, and the frame I is formed with an angular flange I3 extending inward in a plane parallel to the plane of the sash in position to provide an abutment against which the sash seats when the sash is closed. A sealing strip I4 is interposed between the edge of the sash and the opposing edge of the frame I.

The means for connecting the sash 2 to the frame I to permit a limited swinging opening movement of the sash includes one or more spring leaves I5. The spring leaf is usually flat and of stainless steel, and one edge thereof extends into a recess or slot I6 in an upright member of the window frame and open at one end toward the edge of the opposing frame `member of the sash, and the other end of the spring extends into a complemental recess or slot Il opening through the edge of the opposing sash frame member and preferably alined with the recess or slot I6, the outer side wall of the recess or slot I1 being .provided by a portion of the retaining vplate II.

The opposite ends of the leaf are secured to the frame I and to the -sash 2 as by screws I8 and I9 respectively, the screws I8 extending through holes in the frame and into threaded openings 20 in a reinforcing strip 2I on the leaf I5. The reinforcing strip 2| serves as a nut. The leaves extend across a clearance or space IIIA between the confronting faces of the adjacent upright frames members of the window frame and sash, which clearance permits iiexing of the leaves. The frame I is formed with unthreaded bores 22 for receiving the ends of the screws I8.

The opposite edge of the leaf is formed with countersinks or perforated bosses 23 for receiving the heads of the screws I9, the latter threading into the sash 2. One side of the slot or recess I'I in the sash 2 diverges towards the edge of the sash to permit the iiexing movement of the leaf during the opening of the sash 2 and likewise, the opposite or edge of the sash toward the exterior of the car body diverges as at 24 from a complemental diverging face 25 on the frame I to permit the opening limited movement of the sash. The sealing strip I4 is provided with a ange portion 26 extending between the diverging surfaces 24, 25.

The leaves I5 are here shown as mounted on an upright member of the frame I, preferably the upright member toward the front of the vehicle, with respect to the direction of travel, so that the rear end of the sash swings as a wind wing outward, as indicated in broken lines, Figure 2.

The sash is heldciosed by a latching` device 21, this being so constructed that it is .difficult to operate by curious persons or tamperers. The

construction of the latch forms no part of thisY invention.

In operation, when the latch is unlatched and an outward force applied tothe sash ofthe interior of the bus body, thesash;,will'swingout- Ward a limited amount and the leaves flex an amount determined by the divergence of the surfaces 24, 25, and of the wall ofitheslot-:or recess I1. Owing to the relative arrangement. of the hinge leaves, no extra space in a widthwise directon is required, and owing to the hinge leaf there are.; no hinge joints'tol loosen and the-em tire; structure isA particularly compact and' also the sash1;is;nested-weather tightlyxin the window frame,V
